Y The inner wall members have their side edges beveled as at 28 between. i

The upper end of the molding` cavity 27 is closed by a head member 29 in the ferm ol' a bottom of the molding cavity, the wall niemf frame and in cross sectionis of a contour.

sustantially the same asv the cross sectional contour oli' the bottom 6. 4The head piece 29 ,l is formed with spaced vertical flangesl 30', 31 and with the flange 30 'bearing against the .inner face of the outer wall members and llushvwith the tops of these latter. The flange 31 bears against the non-we`bbed face of the inner wall members and is flush with the topsthereof. The flange 31 is arranged be` low the flange 30. The head piece 29 has vent openings 32. The head piece 29 providesthe top wall ol" the molding cavity', the n bottom 6 ofthe body portion 1 provides the bers 14 to 17 form the outer wall of the molding cavity and the wall members 22 to 25 i provide the inner wall of the molding cavity.

Associated with the wall members 22 to 27, as well as being'adjustably connected to the top of the core 10` is a retainer member for the'wall members 22 to 27 and for the to provide a mitre oi'nt therei and which is positioned at the head piece 29. The retainer member is in dicated at 32and includes a depressed part formed with a boss 33 on its upper lace. The boss is-located centrally ofthe member 32 and the latter is formed with an opening 34k extending therethrough and also through the boss- The non-depressed part 35 of the retainer member 32 seats on the top edges of t-he Wall forming members 22 to 27 and on the ange 31 ofthe head piece 29.A

Secured to theV top 11 of the core 10 and eX- t'ending through the opening 34 in the retainer member32 is a threaded stem 36 carrying alwheel 37 stem 36- and engages the boss 33 for the purpose of clamping the retainer member32 in the position as shown in Figure 3 and which will retain the head piece 29 in position. The head piece'29 acts asa means for bracing the wall members 14 to 17i'elative to the wall members 22 to 27.

When the mold is employed the retainer member positioned and after the cement has been supplied to the molding cavity 27,

the retainer member 32 .is removed and head piece 29 mounted in position at'the upper end of the molding cavity and upon thervcement.

'llheretainer member 32 is then arranged inL position andretains the head piece 29 at the top of the molding cavity until the block dries.

ot' trunnions-33 so that it can be turned to vdump the molded block therefrom,after the retaineiinember 32`and head piece 29 have which revolves relative to said" The body portion 1 is provided with apair j been removed therefrom. The head piece 29 carries a pair of handles 39 to facilitate the removal and positioning of the sameiwith re` to the top of the molding cavity 27.

spee't and head piece The shape of the bottom 6 29 provides on the molded block 40 a rounded continuousrib 41 atits top edge and a con-` v tinuous coiicavity 42 at its bottom edge wlierej by when the blocks 4() are arranged in superposed relation they will interlock"or'interengage with each other. p

'If it be desired to provide the bottom of the block llat, a liller member 43 bottom of the molding cavity 27. See Figure 7.

To provide one of the walls of the block with a flue opening'the wall forming mem-V bers 15 and 26 are removed and Wall forining members 44, 45 are substituted therefor 'and in this connection see Figures 5 and 6 which illustrate afmold for manufacturing concrete blocks ofthe form shown in Figure 9 and indicatedV at 46. The flue opening formed in one of the walls of the block 46 is indicated at '47. In the modied form of is employed moldl shown in Figures 5. and 6 the core 43 f which is integral with the bottom 49 of the body portion 5() is formed slightlydiilerent `from the core 10 and in this connection one f side yot the core 48, said side indicated at 49,

has an inset upperl part 50 which provides a shoulder 5l. See Figure 5. l VOtherwise vthan'that as stated the core 48 is constructed similarly to the core 10. TheV wall forming .member 44 is formed with an inwardly extending portion 47 of annular.v form-*and closed as at 50'. at its inner end. The wall forming member is provided with an outwardly extending annular part 51 closed at its outer end as at 52.V rl`he parts 47Y and 5l oppose eachother, as well asabut each other When the wall forming members 44 and 45 are arranged in position.` Seev Figure 5. The wall forming member 44 has outwardlyv extending lugs 53 which abuts the body portion 50. The wall forming member 45 has lateral lugs 54 which abut the part 50 and shoulder 510i the side 49 of the core l48.V The parts 47 and 5l are surrounded by a sleeve or thiinble 55 having its outer end vformed with an outwardly extending ,lateralV iange 56. The sleeve 55 extends from the wallV forming member 44 to the wall forming member45. See Figurev 5. Otherwise than that as stated the construction of the mold shown in Figure bis the same as that shown in Figures l to 4 and the parts of the mold shown in Figures 5 and 6 which correspond to the parts shown in Figures y3 and 4 are provided with reference characters corresponding to y those employed in Figures 3 and 4.

j The brick shown in Figure 10 is indicated at 57and has a flat bottom 58.

. The construction ot the mold as illustrated and described provides tor i expeditiously molding hollow, four walled concrete blocks y with or without afflue opening and with the outei' faces of the walls of the block simulating superposed courses of bricks and suoli simulation is provided by the beads 19, 19. Owing to the manner of setting up the core with respect to the bottom of the body portion and further owing to the manner oi' sealing the molding cavity wat-er or creosote isprevented :tromentering the molding cavity from outside of the body portion or Jfrom i within the core.

It is thought the many advantages of aV Y .mold for the purpose set forth and in accordance with this invention, can be readily understood, and although the preferred embodiment of the invention is as illustrated l, and described, yet it isto be understood that changes inthe details of construction can be had which fall within the scope of the invention as claimed.
